Go to Findagrave.com. I have photographed an impressive looking monument to Civil War Confederate POW's interned in Oak Hill Cemetary, Evansville, IN. They were being treated and died at the Marine Hospital-the first hospital in this area on the westside of Evansville near the Ohio River.
It lists the names of 25 soldiers who were buried in the cemetary in unknown locations. I didn't know if you all knew about this or not. It took my breath away when I saw it.
Click on the photo to read the names. My pleasure to add to the rich history of Indiana.
